My camera came with a p.c. adapter which bayonets into the flash connector of my camera.this will enable me to use any electronic flash with a p.c. cord connection.I have no idea where they can be obtained.Any info would be useful to other combat graphic users.

PC sync cords are fairly common. It's best to start with whatever electronic flash you have, then have Paramount Sync Cords make you a custom cord for your set-up, meaning a PC connection on one end, and the proper plug for your flash on the other.

The 70mm combat graphic has a 1"
diameter bayonnet fitting for flash connection.you need the special adapter that fits this connection and has a pc connection on the other end.
the bulb flash unit that came with the camera is in perfect working connection,but at several dollars for each flash bulb regular use is out of the question.this is why electronic flash is the best option.

After a long absence, I just revisited the Paramount cords site that alecj provided the link to, above, and found that their home page now has a "Vintage" window to click on, down at the lower right. Clicking it brings up a special page just for Graflex. Neat! They must have had enough business from us to warrant creating this option.
